The Friends of the Wissahickon is the oldest and largest of the nonprofit, volunteer groups active in Philadelphia's Fairmount Park system. For over eighty-five years we have been stewards of Wissahickon Valley Park, the beautiful northern stretch of Fairmount Park. Our members maintain and preserve trails and historic structures, care for native plant and animal species, and protect the watershed.

FOW's Trail Ambassadors are trail guides who assist and educate people in the park, and offer guided hikes throughout the park that cover topics such as park history, geology, and ecology.
